National Instruments cDAQ-9179 CompactDAQ Chassis

The CDAQ-9179 (Part number: 783597-01) CompactDAQ Chassis can be used with Scanned C Series modules. These modules are simple input modules that contain a single A/D converter and multiplexer to choose between different information channels. When the cDAQ module interface gets a Sample Clock, it begins creating a Convert Clock for each checked module in the present undertaking. Each Convert Clock flags the procurement of a solitary channel from that module. The Convert Clock rate relies upon the module being utilized, the quantity of channels utilized on that module, and the framework Sample Clock rate. The NI device is equipped with 14 slots, has a USB 3.0 bus connector, and a timing resolution of 12.5 ns. It has a maximum required input power of 25 W.

The cDAQ 9179 driver, NI-DAQmx, picks the quickest change rate conceivable considering the speed of the A/D converter for every module and includes 10 μs of buffering between each channel to take into consideration a satisfactory settling time. This plan empowers the channels for rough concurrent testing. If the AI ​​Sample Clock rate is too quick to consider 10 μs of cushioning, NI-DAQmx chooses a change rate that places the AI ​​Convert Clock beats equally all through the example. NI-DAQmx utilizes a similar measure of cushioning for every one of the modules in the assignment. To unequivocally determine the change rate, utilize the ActiveDevs and AI Convert Clock Rate properties with the DAQmx Timing property hub or capacities. Simultaneous sample-and-hold (SSH) C Series simple input modules contain various A/D converters or hardware that permits all the information channels to be tested. These modules test their contributions on each Sample Clock press. The NI-DAQmx driver software is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabVIEW Real-Time module, LabWindows/CVI, or Measurement Studio.

The cDAQ suspension on the NI cDAQ-9179 bolsters a maximum of two synchronization pulses signals arranged for the user’s framework. This constrains the framework to two assignments with various oversample clock time-bases.

The NI device weighs 51.7 oz, and measures 15.99 x 3.47 x 2.52 in. in physical dimensions. It has a recommended operating temperature range of -20 °C to 55 °C.
